Black seed (Nigella sativa) is a flowering plant native to Asia and the Mediterranean. Its seed has been used to make medicine for thousands of years.
Black seed might help boost the immune system, fight cancer, prevent pregnancy, reduce swelling, and lessen allergic reactions by acting as an antihistamine.
black seed is used to treat asthma, hay fever, diabetes, high blood pressure, eczema, weight loss, menstrual cramps, and many other conditions, but there is no good scientific evidence to support many of these uses.
